“A picture is worth a thousand words. How many words is a video worth?” says Alexander Hoereth, developer of Featured Video Plus, a WordPress plugin. He has programmed an awesome WordPress plugin that allows you to display featured videos in place of featured images i.e. post thumbnails.
By default WordPress doesn’t allows you to crop your post’s featured images (thumbnails). This tutorial is on a simple WordPress plugin: Crop Thumbnails which enables powerful image cropping functionality in WordPress. With this plugin you can crop images directly from post admin (add new & edit) pages using same old featured image metabox.
